Light Pollution

All over the world, people are losing night. In fact, 80% of the global population cannot see the Milky Way from where they live. How can this be?

Light Pollution

Those of us that live on the Western Slope are no stranger to spectacular scenery. The jagged peaks, chiseled canyons, and expansive plateaus of western Colorado are treasures that we all cherish. But one of our most spectacular natural wonders may also be one of our least appreciated: our incredibly dark and pristine night skies.

The term Light Pollution refers to excessive and glaring artificial lighting, especially light that is scattered above the horizon.  This is a very serious problem for astronomers, because it can prevent them from seeing objects in space.
